Defense-in-depth flagged by both pre-release reviewers (Opus + Codex), both
non-blocking but cheap on a credential-handling surface:
- reject any non-http(s) HERMES_WEBUI_RUNNER_BASE_URL scheme at construction
(a misconfigured file:// / ftp:// can never reach urlopen);
- route requests through an opener that does NOT follow 3xx redirects, so a
misbehaving/compromised runner cannot smuggle the Bearer token to another host.
Both operator-misconfiguration-only (not user-reachable). +2 regression tests.

Opt-in HTTP runner-client boundary for the runner-local runtime adapter
(RFC hermes-run-adapter-contract / #1925, Slice 4c/4d). Default-OFF:
without HERMES_WEBUI_RUNNER_BASE_URL the factory preserves the bounded
'not configured' path; when set, WebUI acts only as a JSON HTTP client +
SSE bridge for start/observe/status/controls without owning runner maps.
New api/runner_client.py + additive _runner_* helpers in api/routes.py;
no change to the live _run_agent_streaming legacy path.
